Blindfolded? On the contrary, quite watchful! (4-4)
I believe the answer is:
open-eyed
But I can't explain it at all! Could you help me understand?
(Other definitions for open-eyed that I've seen before include "Astonished; fully aware" , "Astonished - watchful" , "Forming an encrusted mass" , "Surprised - aware" .)
